Check Digit Verification of cas no

The CAS Registry Mumber 144539-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,5,3 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144539-63:
(8*1)+(7*4)+(6*4)+(5*5)+(4*3)+(3*9)+(2*6)+(1*3)=139
139 % 10 = 9
So 144539-63-9 is a valid CAS Registry Number.

Studies on the synthesis of chlorothricolide: Diastereo- and enantioselective syntheses of model top-half spirotetronate units

Roush, William R.,Sciotti, Richard J.

, p. 5473 - 5482 (2007/10/03)

Highly enantio- and diastereoselective syntheses of spirotetronates 9 and 10, corresponding to the top-half fragment of chlorothricolide, are described. Key steps in these syntheses are the Diels-Alder reactions of trienes 11 and 12 with the chiral dienop
